Fertilization and watering are very important during onion planting. If not done well, it will seriously affect the quality and yield of onions. The grower Li Dacai made the mistake of not watering and fertilizing, resulting in extremely low onion production. Let's see what happened to him. The onion grown by Li Dacai, a grower this year, was laughed at by people for a few days: "No watering or fertilization will be done. It will also plant seeds and waste seed money." Li Dacai said, "I will not be you." Yes, look at who can produce high yields this year, so bet on it. Li Dacai is a relatively diligent person. He goes to the ground every day. At first he looked at the growth. It was not bad. It was slowly found that the yield was very low, and the onions were not as high as others, and even yellowed. Thinking of his bet, Li Dacai began to panic. Going to the store to buy some nutrients sprayed, no effect. It's best to find me: You see, this onion won't be sick! I veto directly: they are really right, you really don't water or fertilize. When I finished, his face changed. Here are the methods for watering and fertilizing: First, watering The onion should be watered immediately after planting. This is called planting water. When the seedlings enter normal growth, care should be taken to water them according to the following principles and methods. Watering principle: control the water during the seedling period; watering the leaves during the vigorous growth period, pouring it once every 7~10 days, keeping the soil dry and wet. The seedlings were controlled 7 to 10 days before the bulbs were inflated, which promoted the growth of the leaves to the bulbs. In the bulb expansion period, the number of watering is increased, and it is poured once every 6-8 days; the watering is stopped 7 to 10 days before harvesting, and the water in the bulb is reduced, which is more convenient for storage. You can choose from a variety of methods for watering, such as: watering, furrow irrigation, sprinkler irrigation, drip irrigation, etc. It is best to sprinkle irrigation and drip irrigation, and do not advocate flood irrigation. Second, fertilization Fertilization according to growth conditions, the rapid growth of nitrogen fertilizer should be applied in the vegetative growth period to promote plant growth. In the early stage of growth, it is necessary to reduce the amount of water and fertilizer. In the spring, the first fertilization is carried out after 2 weeks of planting, and the planting is carried out before winter. It can be applied with urea, applying 5~7.5 kg per acre; when the plant enters the vigorous growth period of the leaves, the second top dressing is applied, and 5 to 7.5 kg of urea and potassium sulfate are applied per mu, and then the top dressing is followed by the top dressing. ~2 times. After the end of the seedlings, that is, at the beginning of the bulb expansion, with the watering, the fertilizer is applied, and 10~12 kg of urea per mu is applied; in the middle of the bulb expansion, the fertilizer is applied again, 8-10 kg of urea per acre, and 8 kg of potassium sulfate. After the grower Li Dacai heard it, he found that he really didn't water and fertilize. It seems that he wants to plant the onions. It really takes more effort! The farmers friends should pay attention to it. Don't care about planting anything, watering and Fertilization is a very basic job and must be done well.
